Antacids help to treat heartburn (indigestion). They work by neutralizing the stomach acid that causes heartburn.
You can buy many antacids without a prescription. Liquid forms work faster, but you may like tablets because they are easy to use.
All antacids work equally well, but they can cause different side effects. If you use antacids often and have problems with side effects, talk with your health care provider.
Heartburn - antacids; Reflux - antacids; GERD - antacids
When to Use Antacids
Antacids are a good treatment for heartburn that occurs once in a while. Take antacids about 1 hour after eating or when you have heartburn. If you are taking them for symptoms at night, DO NOT take them with food.
Call your provider if you need to use antacids on most days.
Side Effects of Antacids
You may have side effects from taking these medicines. Antacids are made with 3 basic ingredients. If you have problems, try another brand.
Antacids can change the way your body absorbs the other medicines you are taking. It is best to take any other medicine either 1 hour before or 4 hours after you take antacids.
Talk to your provider or pharmacist before taking antacids on a regular basis if:
